APPLIANCE FOR PREDETERMINING SPEED.

SPECIFICATION forming part of Letters Patent No. 687,233, dated November 26, 1901..

Application filed February 14, 1901. Serial No. M369. (No model.)

To aZZ whom it may concern.-

Be it known that we, DAVID H. HILTON, a resident of Jersey City, in the county of Hudson and State of New Jersey, and EDWARD N. GAUDRON, a resident of New York, Brooklyn borough, in the county of Kings and State of New York, citizens of the United States, have invented certain new and useful Improvements in Appliances for Predetermining Speed, which improvements are fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a side elevation view of an appliance for predetermining speed constructed in accordance with our invention. Fig. 2 is a central longitudinal section of said appliance. Fig. 3 is a horizontal section taken along the line a a of Fig. 1. Fig. 4 is a sectional fragmentary view of a sound-reproducing machine, our improved appliance being illustrated as mounted thereon for practical service.

Similar reference numerals denote like parts throughout the several views of the drawings.

This invention relates to improvements in devices of that class which may be designated appliances for predetermining speed, the same being designed for service in connection with a revoluble part or parts for the purpose of predetermining the velocity or rate of speed at which such part or parts shall revolve under duly-applied power or energy.

The object of the invention is to provide an appliance of the character above indicated which shall be simple, inexpensive, and novel as regards construction, efficient in operation, and which shall admit of being readily attached for service to a mechanical structure, as a phonograph or analogous sound-reproducing machine, embodying a revoluble part or parts.

The invention consists in the employment of certain parts novel in the matter of form, in the novel disposition and arrangement of the various parts, in certain combinations of the latter, and in certain details of construction, all of which will be specifically referred to hereinafter and set forth in the appended claims.

In the accompanying drawings the invention is represented as applied to a phonograph; but said invention may be availed of in connection with other mechanical contrivances embodying a revoluble part or parts the speed of which it is desirable to predetermine.

Having reference now to the accompanying drawings, 2 denotes a bed-plate having attached to the under side thereof a horizontal frame 3, from which depend a hanger 4 and oppositely-arranged bearings 5 5, in the lower extremity of which bearings is mounted to rotate the governor-shaft 6, provided with elastic elements 7 7, the former of which carries the governor-ball S and the latter the governor-ball 8. There is also firmly mounted on the governor-shaft 6 a friction-disk 9 and a pinion O, the latter adapted to mesh at all times with a member of a suitable train of gear-wheels, spring-actuated or otherwise impelled, and whereby under certain conditions a rotary motion is imparted to the record or cylinder 10. The lever 11 is mounted to work on the pivot 11 and is provided at its lower extremity with a shoe 11 for engagement with the disk 9 and whereby a braking effect for the movable parts of the device as a whole may be had through proper manipulation of the said lever 11.

12 is a spring-controlled arm mounted also to Work on pivot 11 and having at its lower extremity a shoe 12, adapted under normal conditions to have frictional contact with the disk 9 through the action of spring 12.

The parts thus far described are of ordinary construction and are assembled in a manner well known in the art. The speed of the intermeshing parts is regulated in common practice through variable downward tilting of the arm 12 against the action of spring 12", thus causing the shoe 12 to engage the disk 9 with variable degrees of friction. To accomplish this variable tilting of the arm 12, there is ordinarily provided an adj ustingstem, as 13; but it is further essential that means be provided whereby the range of ad- 4 justment of the stem 13 or degrees of such adjustment of said stem may be determined and indicated, to the end that the speed of, say, the

governor-shaft 6 may be predetermined with respect to the starting of said shaft in motion. Such means are embodied in our improved appliance, which will now be described.

14 represents a graduated member, on and for cooperation with which is pivotally mounted a pointer 14, and 13 represents an adj usting-stem having a threaded engagement with the frame 3 or analogous part, and consequently arranged for movement longitudinally and rotarily, and the member 14 is arranged parallel'with the stem 13.

Connections whereby upon movement being imparted to the stem 13 due movement will be imparted to the pointer let are interposed between said stem and said pointer, and such connections are here illustrated as in the form of Worm-teeth 15 along the circular edge of the pointer 14 and in the form of threads 15, arranged along the stem 13 or part carried thereby when conditions prevail under which said part and said stem act as a unit, and in this connection the said threads are in mesh at all times with the said wormteeth.

16 is a sleeve let onto the stem 13, and as these parts are adapted to act as a unit when the set-screw 16 is turned home the said sleeve is shown as having formed therealong the threads 15.

17 is a collar formed integral with or secured in any approved manner to the graduated member 14 at the upper extremity thereof, and 17 is a base also formed integral with or secured in any approved manner to the graduated member 14 at the lower extremity thereof. The base 17 approximates in character the collar 17, and under normal conditions the latter engages the sleeve 16, while the former engages the stem 13. The lower end of the sleeve 16 serves as a stop or shoulder, between which and the base 17 we interpose an elastic element 18, (here shown in the form of a spiral spring,) and the base 17 is also provided with one or more spurs or pointed projections 18, the purpose of which will appear hereinafter.

The stem 13 may be provided with any suitable finger-piece or with a milled head, as indicated in the drawings, and which may be grasped by the user when desiring to impart movement to said stem.

In practice the stem 13 engages at its lower end, through the medium of the threads there located, the frame 3. The user moves the sleeve 16 to a suitable point along the stem 13 against the action of the element 18 and looks it in such position by turning the set-screw 16 home. Under these conditions the sleeve 16 and stem 13 operate as a unit, and the ele ment 18 will tend to urge the base 17, and consequently the member 14:, downwardly or away from the head of the stem 13, and thus yieldingly hold the spurs or projections 18 to a serviceable engagement with the bed 2, particularly if the latter be enameled or of material capable of being indented. Thus it will be seen that the graduated member 1t under these conditions is yieldingly disposed.

It will be understood that means other than such as described may be employed for holding the base 17 to serviceable engagement with the bed 2 and also that connections other than the teeth 15 and threads 15 may be interposed between the pointer 1 1 and the adj usting-stem 13 and whereby when said stem is moved said pointer will be moved.

The record or prepared cylinder 10 is of ordinary construction and bears a character, as 9, corresponding with one of the characters on the member 14. Further, in operation the user selects a record, mounts it in position for service, turns the stem 13 till the pointer 1-1 registers with the character on the member let which corresponds with the character on said record, and then sets the machine in mo-' tion. The turning of the stem 13 will result in tilting the arm 12 downward, thus diminishing the friction of the shoe 12 on the disk 9, and the governor-shaft 6, record 10, and intermediate intermeshing parts will move at the required speed.

It will be understood that our improved appliance may be modified to some extent, particularly as to the details of the general construction, without material departure from the spirit and principle of our invention.
